SCYTHE-SNATH COUPLING.

SPECIFICATION forming part of Letters Patent No. 360,561, dated April 5,1887.

Application filed June 1, 1880. Serial No. 203,865.

To aZZ whom it may concern:

Be it known that I, GEORGE S. GLow, a resident of North Indianapolis,Marion county, Indiana, have made certain new and useful ImprovementsinScythe-Fastenings, adescription of which is set forth in the followingspecification, reference being made to the accompanying drawings, in theseveral figures of which like letters represent like parts.

My invention relates to the construction of fastenings for connectingthe scythe to the snath, and in the arrangement of the several parts,whereby a compound motion is capable of being given to the scythe, sothat a revolution in a horizontal plane and an adjustment 1n averticalplane are possible, and will be understood by reference to the followingdescription.

In the drawings, Figure l is a front view of my device, showing the tangof the scythe connected to the end of the snath. Fig. 2 is a side viewof the same, the dotted lines indicating the position of the parts whenthe adjustment is made in a vertical plane. Fig. 8 is a vertical sectionon the line w as, Fig. 1. Fig. at is an under View of the upperlockingplate. Fig. 5 is aplan view of the lowerlocking-plate, in whichthe plate Z is adapted to fit. This figure also shows the position ofthe under locking-plate in the head. Fig. 6 is a side View of theloop-bolt that connects the plates together. Fig. 7 is a side view ofthe head of the plate, showing the recess in which the locking-plate Zfits and within which it is adapted to rotate. Fig. 8 is a reverse sideView of the under locking-plate, Z, a front view of which is shown inFig. 5.

In detail, 1) represents a metallic plate, having a loop socket or band,I), which goes over the head of the snath h and is riveted to the side,as shown in Fig. 2. Above this band is an extension of the plate, 9,forming a means of connection for the other parts. This extension 1), atits upper end, is recessed at 1-, as shown in Fig. 7, the bottom of therecess being slightly corrugated, and in this recess an underlockingplate, Z, having similar corrugations on its under side, fitsloosely, so that when the corrugations on its under side do not engagewith the corrugations in the recess of the plate the underlocking-plate, Z, may be rotated in (No model.)

a horizontal plane in such socket. This provides for one of the twoadjustments of the fastening herein described. This under locking-plateis channeled out on its upper side, as shown in Fig. 5, the two outsbeing at right angles to each other; but an opening is left entirelythrough this plate to receive the head of the loop-bolt shown in Fig. 6.One of these channels is corrugated, as shown, and the upper lock-plate,Z, is provided with projections on its under side, which are also 001rugated to correspond with and fit in the corrugations on the underlock-plate, Z. When this upper locking-plate is set inthe lowerlocking-plate, Z, so that the teeth on its projections will engage withthe teeth in the re cess of the lock-plate Z, an adjustment is possible,so that either one side or the other may be raised or lowered in orderto change the angle at which the blade of the scythe enters the grass.This movement is indicated in dotted lines in Fig. 2. The tang of thescythe (shown at t) passes through the eye of the loopbolt 6, over theupper locking-plate, the end of the tang passing down and abuttingagainst the end of the lock-plateZ and between projections formedthereon, as shown in Fig. 4.

In Fig. 3 is shown a vertical section of the parts arranged in properrelative position,and when they are in place they are secured by the nutn,working on the threaded end of the loopbolt e. If when in use it isdesired to throw the point of the scythein or out in relation to-thesnath, this movement is accomplished by loosening the nut n andrevolving the parts upon the bearing of the lower locking-plate, Z, thedotted lines in Fig. 1 showing this variation in the position of thetang and heel of the scythe.

If it is desired to vary the angle with which the edge of the scythewill strike the grass,the nut n is loosened and the lock-plate Z is somoved as to throw one end farther out or in upon its seat in the lowerlocking-plate, Z, and then by tightening the nut the parts are held inthe desired position. I thus provide a cheap compact device which willallow a double movement of the scythe with relation to its connectionwith the snath, as hereinbefore described-viz., a movement in ahorizontal plane, so as to throw the end of the scythe ICO out or in, ora movement in a vertical plane, so as to change the angle with which theblade strikes the grass.

Usually the tang of the scythe is made relatively longer as comparedwith the plate than the one shown in this device, and the end of thetang fits into an opening in the plate just above the rivet. I haveimproved upon this construction and shortened the tang or heel of thescythe, turning down one end of it and causing it to pass between smallproject-ions formed on the end of the upperlocking-plate, Z, as shown inFig. 4-. This provides asimple and secure support for the end of thetang, the projections acting as guides to keep it from slipping fromeither side.

I am aware that scythe-fasteners allowing certain adjustments are notnew, and do not broadly claim the same as my invention; but

\Vhat I do claim, however, as myinvent'ion, and desire to secure byLetters Patent, is the following:

1. In a scythe-fastener, a plate having a band to receive the head ofthe snath, its extension recessed to admit a circular locking-platerevolublein such recess, and an upperlocking plate provided with teethfitting upon corresponding teeth formed in the front side of suchcircular locking-plate,to allow an adjustment in a plane at right anglesto the plane of revolution of the circular locking-plate, all the partshaving openings to admit a bolt provided with a loop on one end to admitthe tang of the scythe, and threaded to receive a nut on the other end,whereby the parts are held together, substantially as described.

2. A scythe-fastener having a double hearing interposed between the tangof the scythe and the plate secured to the snath, said double bearingbeing formed of two interlocking plates, the upper one of which isadjustable in the lowerin avertical plane, thelowcr plate interlockingin an opening formed in the plate secured to the snath, and revolubletherein in a horizontal plane, the parts being held together by a loop,bolt, and nut, substantially as described.

3. In a scytheiastener, the plate 1), having band I) to admit the headof the snath, the extension p, having corrugated circular recess r toreceive the circular locking-plate Z, corrugated on its under side tofit the teeth in the recess 1' and channeled on its opposite side toadmit the ribbed projections formed on the under side of the upperlocking-plate, Z,which fit into such channels, allowing an adjustment ofthe two plates with respect to each other, the bolt 6, having a loop onits upper end to admit the tang of the scythe, and the nut a on itsopposite threaded end, and the tang tof a scythe, all combinedsubstantially as described. 4. In a scythefastening, the plate 12, whoseupper extremity is recessed to receive the circular plate Z", revolubletherein, the upper locking-plate, Z, fitting into and interlocking withsuch circular revoluble plate, and provided with a notch to receive theshortened turned'down end ofthescythe-tang,with means for uniting theparts and holding the tang in position when inserted in the notch,substantially as shown and described.

5. In a scythe-fastening, the plate p, whose upper extension. isrecessed to admit the circular plate Z, revoluble therein, and theupperlocking-plate, Z, fitting into and interlocking with such circularrevoluble plate and adjust able therein, all combined substantially asde
